This is weird. My internet service maxes out around 250mbps, and using the Deco mesh system I'm getting impressively close to that over Wifi. However, over hardwired ethernet I'm maxing out at around 99-100mbps. 

This is totally bizarre to me, my old router (a Dlink from roughly a year or two ago) didn't offer the coverage that a mesh system does, but my cat5 connections consistently got approximately the max speed I'm paying for (250mbps). I keep my desktop hardwired for reliability and I'm using the same cables as before so nothing changed other than replacing the previous Dlink router with the Deco mesh. Now, I'm noticing that I unplug my cat5 and turn on Wifi, I get FASTER THAN WIRED INTERNET?! Something is backwards here, right? 

Is there a setting or something I'm missing? What would this be?
